Abstract: A sheet unloading device for use in a printing or duplicating machine, or the like, wherein sheets are delivered seriatim to a receiving tray whereat the sheets are deposited onto the top of a stack of sheets in the tray. An interposer mechanism is movable to an operative position at the end of the tray for dividing the tray into a first, lower portion and a second, upper portion. The interposer mechanism permits removal of the lower portion of the stack while sheets are continuously delivered to the upper portion of the stack. A back stop is provided at the end of the tray and can be selectively lowered to permit removal of the lower portion of the stack of sheets.

Abstract: A mechanism for registering sheets in a printing or duplicating machine which includes a conveyor board for delivering the sheets seriatim to the registering mechanism. A stop guide is mounted on a fixed support of the machine at one side of the conveyor board. A jogger guide is mounted on a jogger device of the machine at the opposite side of the conveyor board. The jogger guide includes a spring loaded blade for acting against a side edge of the sheet to move the sheet laterally to engage an opposite side edge of the sheet against the stop guide. The spring pressure of the blade is adjustable to accommodate sheets of varying weight, and the blade is provided with floating movement to accommodate sheets which are skewed or out-of-square. A calibrated dial is employed for incrementally adjusting the location and spring pressure of the blade. The stop guide and jogger guide are easily converted for left hand or right hand jogging, or vice versa, without removing either guide from the machine.
